Event ID 5120 "Cluster Shared Volume 'Volume1' ('Volume1') is no longer available

I came across this issue with Three nodes cluster in my client setup. So my recommendation to avoid such issue as follows.

1.     Setup the Microsoft Hyper-V cluster with all well planning, test it thoroughly and Follow MS provided Best practices.

          Cluser Based on Windows 2012 Server

         

          Cluster Based on Windows 2012 R2 Server

          And

       

          Also refer  Altaro website

2.     Update Hyper-V Cluster nodes at least quarterly basis for its Hotfixes and  Update.

3.     Apply the hotfixes as per your OS version.
